Haxe

btw, if you are talking about certain backends (kha, raylib & pdcurses come to mind) then essentially everything is virtual

thats because i had to create my own component hierarchy for those backends, so i could make those obvious optimisations easily

well, maybe not a "component hierarchy" (thats haxeui-core), but drawing parent / children / items etc... so its easy when to say "skip this"

although, now i think about it, virtual _will_ still have an effect on those backends... if you had a million list items in a list that could only display 7 then non-virtual containers would create a million components.

with virtualisation there will only be 9 (iirc) - so it would still have an effect - though the threshold at when it becomes obviously needed would be less

I will have to million item a table and see how it custom renders 🙂  Sounds good

yeah, my guess is that kha, raylib and pdcurses will be "ok" (although a pain to initially populate)

they will simply "skip" them when they are offscreen (which includes scroll bounds), but it _will_ still have to go through a million items

with virtualisation it wouldnt, the data scrolls, not the components

in order to make the calculations, items have to be the same height

they can be autosized, but once that height is set for one, it applies to all

so a million items with a big chunk of wrapped text of different sizes aint gonna work well with virtualisation

i dont know a way around that personally... there probably is some smart algo, but i havent invested a huge amount of time / investigation in playing with one

<@!385014891750096896> is it possible to crop an image using the `Image` component? For example, showing just 50% of it horizontally

there are a number of options for images in... ... ... stretch? I think is the prop

if that doesnt work, image-clip-rect is another...

im sure im getting these prop names wrong... two secs

```haxe
@:enum
abstract ScaleMode(String) from String to String {
    var NONE = "none";
    var FILL = "fill";
    var FIT_INSIDE = "fitinside";
    var FIT_OUTSIDE = "fitoutside";
    var FIT_WIDTH = "fitwidth";
    var FIT_HEIGHT = "fitheight";
}
```

and if you just want to cut out a portion of an image

```css
x {
    background-image-clip: t, l, b, r;
}
```

though that only applies to background images i think, not image resources

(its what haxeui uses for slice-9 with the `background-image-slice` css)

might be easier to explain what you are trying to do 🙂

the second one is perfect for what I want, thank you!!

I have a single image that contains 2 frames of an animation. I wanted to take one of them and use as an icon inside a list view
